James Gunn Reveals Why He Changed The Power Stone's Color In Guardians Of The Galaxy

CB: The Infinity Stones have been used as a plot device to connect the Marvel Cinematic Universe. Because of that, you would have thought Marvel Studios had every little detail regarding them, like which color each one is, all planned out well in advance. Today, Guardians of the Galaxy director James Gunn posted an image of the original Infinity Stone of Power and it's red -- as it is in the comics -- but was altered to purple in post after he saw the Reality Stone was red in Thor: The Dark World.
